Method of storing an electrotransport drug delivery device

摘要

A switch operated therapeutic agent delivery device is described. The device comprises two parts, which are assembled by a user prior to use. A first part contains a power supply and circuitry for the device; and a second part comprises electrodes and reservoirs containing the therapeutic agent to be delivered. The action of combining the two parts of the device causes the two parts to be irreversibly coupled together, completes an electrical connection between the two parts, and closes one or more switches, thereby connecting a power source, such as a battery, into the device's circuitry, thereby powering the device on so that it is ready for use. The device can then be attached to a patient, who can operate the device by pressing a button in a proper sequence.

主权项

1. A method of storing an electrotransport drug delivery device to resist corrosion prior to use, the method comprising:
separately storing an electrical module and a reservoir module, so that circuitry in the electrical module is electrically isolated from a power source in the electrical module by a power-on contact between the circuitry and the power source when the electrical module is separated from the reservoir module, wherein the power source is isolated from the circuitry by the power-on contact while the power-on contact is open; combining the electrical module and the reservoir module to form a unitary drug delivery device by connecting the circuitry via an electrical output to an input connector on the reservoir module, wherein combining the electrical module and the reservoir module causes battery contact actuators on the reservoir module to close the power-on contact allowing the power source to power the circuitry; and electrically connecting the circuitry in the electrical module to at least a pair of active electrodes in the reservoir module when the electrical module is combined with the reservoir module.
